This is 100% my point why Chemical cleans are no good for an engine, all that built up crud gets forced through all the area's you pointed out. Cost more for a mechanical removal and clean but all that crap goes in the bin and not through your engine. Catch can can only do there job if fitted from near new, There great, but for a slightly older rig the mechanical clean must come first then fit the can. Now let the money making chemical cleaning guys unleash and tell me where they recon the crap goes if not through the engine, Thanks for your video Murray in Redcliffe QLD.

@@renbenism My intercooler was literally dripping with oil after 5000ks. The oil mist is harmful to the turbo that it passes through and coats the intercooler so it doesn't work nearly as well and it coats the inside of the inlet where the extreme cylinder heat will bake the crud on, even without the addition of EGR. The crankcase blowby fumes are not pure clean oil - the collection of trapped fumes that comes out of my Provent is disgusting black oil. I remind readers that 50% of mechanics are below average, and I remind readers of the oft publicised videos that trap "mechanics" ripping customers off.

[@unofficialtester1545]

@@maxxfx4767 because EURO V and VI emissions which manufacturers abide by in order to sell their vehicles into Europe do not take into account countries that do not see snow. Further more, you can drive for 5 hours in any direction and pass through 2 or 3 countries. In Australia, 5 hours drive would not even get me anywhere near my states capital city. Engines for Euro specs are only designed for short start\stop....not long distance driving. hence why aftermarket addons are needed on vehicles that meet Euro specs but are sold in countries outside of Europe. My town hits a maximum of 42 degrees celsius and roughly 5 degrees celsius in winter. 5 degrees C in winter only happens once every 3 years, usually our average is 13 - 15 degrees Celcius for the winter months. Engines in Europe rarely get to operating temperature before they are shut down and the driver reaches their destination.

[@einfelder8262]

The explanation of how EGR "saves" your engine by de-stressing it is pretty much a politically correct discourse. Yes it reduces NOx emissions, but NO it doesn't give an engine better economy or longevity. To cruise at a certain speed requires a certain amount of energy from the fuel - if you reduce fuel and O2 by filling half the chamber with inert gas you reduce the power output and hence the vehicle will slow down until you press the accelerator further to add more fuel again. Your economy actually gets worse. I've had a Provent on my Patrol since 5000k from new, and the inlet was already saturated with oil - dripped out of the intercooler when I took it off to wash it out. The Provent is indeed an elite quality catch can/oil separator.

[@AaronCook83]

Not sure if the guy knows how diesels operate vs gas. If the ECU is actually reducing fuel, your right foot will be compensating. Give me all the oxygen and all the temperature, the NOx can be treated in other ways.

[@wazza33racer]

exactly. The engine breathing in soot is just destructive to its internals.........and less oxygen thanks to EGR works against all the progress in turbocharging and intercoolers to increase oxygen density. Talk about politically correct bull manure.

Catch can helps like 5..10%, the EGR gases is the main issue, I got a catch can and it catchs some oil, but that does not eliminate the soot on the intake and EGR valve as the gas from the EGR has sooo much oil on it, diesel engines are designed for long time running, I had an mwn diesel bus that ran everyday from 4:30am till 12:30 every day from Mon-Sat, 2 drivers and it has never any issue because it was always driven like pedal to the metal, hard working lot of hours 400k in 5 year, urban drive 14km each trip, probably 15..18 each day

I AM A HUGE FAN OF 4WD ACTION GREAT VIDEOS THANK YOU GUYS! The Manufactures now build cars like throw away cigarette lighters due to fact most of the engines are no good unless you mod them cough cough, they have DPF fitted creating higher engine temperature due to the restriction in the exhaust an EGR that recirculates all the dirty final emission output especially when they are not closing correctly causing smoke less mpg and higher nox! ohhhh and mr Mann filter man..........an egr recirculates the hot exhaust gas so this make the burn temp higher not lower !! I do like the catch can though its good that the crank case oil is not been allowed to enter the combustion process

[@crooked-halo]

I've read the opposite, that since the exhaust gas that recirculates is always losing heat after combustion, the EGR allows _cooler_ temperatures in the cylinders, _not_ higher. This makes more sense logically than what you said "makes the burn temp higher."

[@lewisberry8826]

This doesn’t stop the egr cooler from failing and pumping all ur engine coolant out ur Exhaust or you could replace it every year

[@supernova_akm72]

So the egr lets less oxygen into my cylinder therefore my engine burns less fuel. Never have I heard someone say you to restrict oxygen and fuel. Wouldn't putting a plastic bag over my intake have the same effect without the extremely hot exhaust gas being reintroduce into my cylinder?

[@driveandsurvive]

I had a look at a EGR system with a catch can. It still had plenty of carbon deposits. It may well slow the deposits down as it catches the oil and the soot has less ability to stick to the EGR components and the inlet manifold, but I wonder if the small amount of oil that gets through without a catch can, helps to lubricate any deposits that make their way into the cylinders? Essentially, is the grit post catch can more abrasive as a result of the oil removal?

[@stephensmith5317]

@Charles Martell did you just watch this video at all.

[@tenpercentfordabigguy8550]

If you already have build in the intake ,does it go away after fitting one of these? Or do you need to have it cleaned out first?

[@4x4maximus]

Incorrect! The problem is the EGR soot. You need to reduce that by a blanking plate, generally a 7mm to 8mm hole blanking plate will significantly reduce build up. You have butterfly valves and the valves that need lubrication from vented engine gas. Diesel use to get this lubrication before direct injection. Now diesel is directly injected it bypass the additional lubrication diesal inlets need. Reduce EGR soot and leave the oil, the oil will act as a cleaner and remove the reduced soot. Taking away the lubrication the soot will still cake your inlet. Reduce EGR and keep engine gas recirculation. It's minimal oil! Have you ever check your oil and noticed it dropping? No! If your worried about intercooler reducing its cooling efficiency, pull it off every service and high pressure clean it out. It's only 4bolts and 2 hose clamps. Again it's not blanking it reducing EGR by 90% it still gets through just slower

[@makusmati]

This is a good point everyone may have missed if it's true but what you are saying is that the swirl-flaps fitted in the inlet manifold need lubrication from the blow-by oil?

[@Fernweh4x4andadventure]

So your putting burnt oil back through the pistons cycle, so it lowers diesel consumption and pressurises the crank case! Why not just have hho run back through? (because the o2 sensor sensors fuel and supplies the right amount of diesel). Then you can catch 100% of the oil, it would still lower fuel consumption and be 100% better for environment and the engine, and the oil discard process might be higher but a lot easier and the whole system works better all round?? 💁🏼‍♂️ Can an egr sensor be deleted from ecu ? And can it “sense” Hydrogen as a fuel or be changed to do so??

[@PedroQ105]

The catch can is somewhat not a very dependable solution since the oil vapour from the blowby gases makes the soot from the EGR stick on the inlet assembly instead of it going directly into the combustion chamber where it can be abrasive to the cylinder walls and piston rings. Just clean the intake assembly after 80,000 kms you'll be fine. Instead of prematurely wearing out the cylinder walls and piston rings which is more expensive than cleaning the just cleaning the intake.

[@pauldarlington5589]

I have heard this argument before, but I believe it has an obvious flaw to it. If the exhaust gasses are abrasive to valves, cylinder walls and rings then consider that these components are exposed to exhaust gasses constantly while the engine is running. The only engine cycles with little to no exhaust gasses present (EGR gasses present in the cylinder) are intake and compression. I tend to believe it's far preferable to avoid choking the inlet with a soot and oil mixture.

[@snowrider141]

If the EGR been deleted/blocked. Will the catch can still work?

[@VictorToursVictorHarbor]

Why dont manufacturers include catch cans from new?

[@tmmtmm]

Because they still have to vent the pressure from the crankcase somewhere and the only legal place to vent the pressure is back into the intake. Effective filtering is at odds with relieving the pressure from the crankcase. A filter that catches every last bit of oil will be too restrictive to prevent pressure building in the crank case. That's why most aftermarket catch cans vent to atmosphere because it completely solves the dirty intake issue and they don't care if some oily vapours make it to the atmosphere - they are however illegal. A complicated catch can also adds extra cost to producing and servicing the vehicle and every dollar is important if you're in the business of selling and servicing vehicles.

[@lukepaul2882]

TMM if you watch closely the catch can only catches the oil and the blow by pressure still goes into the intake. So I can see why he said why don't manufactures do this from the get go.

[@tmmtmm]

@@lukepaul2882 yes, so it does not completely solve the problem. Less oil will make it to the intake but there will still be some oily vapours vented into the intake and the crankcase pressure will be higher as a result of the restriction that the can makes. Whether or not this is enough improvement that it is worth doing and doesn't cause negative effects I couldn't tell you.

[@stephencomando9206]

A piece of the picture nobody seems to mention is the answer to your specific question. The answer is because if the oil catch can is not maintained properly, this can cause more damage to the engine than not having an oil catch can in the first place. As some people mention, many people do not regularly service their vehicles properly or enough. This introduces a very real problem and concern for the manufacturer to deal with. In addition, unless the vehicle is Direct Injection, the issues created by not having a catch can are typically not an issue until after the car is out of the warranty period. In the case of Direct Injection vehicles, some manufacturers are utilizing other methods to stem a part of this problem (typically carbon build-up on the valves in particular).

Direct injection petrol engines have the exact same problem ad diesels. There ya go.

Great explanation, thanks. Does fitting a catch can affect new car warranty in my case 2022, Toyota 79 series V8 ?

[@Psilocybiant]

So the EGR doesn't engage at full power and at full temperature but its suppose to reduce engine temperature........riiiight..

[@drew377]

Careful with your factory warranty if fitting catch can to new vehicle... peanuts @ Toyota service centre told me the warranty would be voided if I put my catch can on my new Hilux. I said - warranty voided by in-line filter?? Why?? They said - "after-market modification, automatic void of warranty". What tools. Anyway have to wait 3 years before fitting now...

[@praetorian3571]

Catch can severely damage your engine!! Toyota was kind of enough to warn you about not installing the catch can.

[@adriankiraly5172]

Question: if an oil separator is so effective, why don't manufacturers fit it at the factory?

[@UnacceptableViews]

they aren't fitted as standard because 90% of people wouldn't empty them at the intervals they need to be emptied. sucking in actual liquid oil would cause more damage than oily gases.

[@adriankiraly5172]

@@UnacceptableViews well, they could've make it part of the service schedule (like checking/replace mthe PCV valve since the 70's) it is like who the hell will clean a MAF...

[@HYITHO]

Dumb question, how come these are not sorted out by the manufacturer? As in what stops them from installing a catch can from the get go?

[@Bananas1973]

1. The engine will last the warranty period with or without one, saves them money to not fit them. 2. As the expert said, it needs to be maintained (emptied) every 5'000kms. If its not emptied and becomes full, it causes bigger problems - excessive pressure build up in engine and can damage engine seals.

[@Jason-yg9fe]

Hi I have recently had a catch can installed about a month ago all I have had is abit of water come out when I drain it. It's been opened up and has a build up of grease around the rim of the catch can. Do you know if this is a problem for me in the near future? Is it doing its job?

Ive just installed one on my Diesel 2.8 intercooler Jeep. 08 wrangler done 200k. Those L shaped joiners concern me!? Surely they will make the breather return tubes squirt like a water blaster jet? This was a kit with all of the bits and pieces of pipes and L shaped [internal] connectors etc... This is going to annoy me until I change those small L shaped joining internal corner pipes out.

[@waynewalker7410]

Guys I need some help here. I have a 2015 Mazda Atenza AWD twin turbo 2.2L diesel and I just cleaned my EGR and Manifold. Which of these catch cans will work for me?

I have a 1994 70 series with a 1KZ-T engine. I guess i don't have to worry aboit this

I ve seen some people installed 2 Catch Can for a better result. Why not most of the racing cars in the circuit have 4 Catch Cans installed to get a maximum performance.

[@sandragreen1898]

Sold once again, you guys keep on delivery the goods haha built not brought 💪

[@Bootlerov]

Oh boy! At 1:07 and 3:47. WHY?! would you reduce the cross section of the plumbing to/from catch can? You did show how much of blowby diesel has. The way it looks you "acheived" 50-75% flow resistance depending on the size of that 90deg adaptor. PV200 is rated for engines under 200kW and has 25mm inlet/outlet for a reason, whereas PV100 for under 100kW - 20mm. Your longish lines already introduce enough restriction.

[@NZbluesky]

I was thinking about that whole scenario of those 9o degree connectors at 3.47 minutes. I have just installed this and I had to use 3 of those L shaped connectors!?

[@gsd4me00]

Very informative. As blanking off the EGR valve is not a good idea, does that also go for a EGR delete cable such as the Munji brand?

[@AJByrne82]

David Hunn I’d say so as I have one on my Holden Rodeo for some time now as I’m planning to do a full carbon clean to the engine as a precaution I think now it’s is the time to switch over to a catch can setup. More on the peace of mind, don’t get me the wrong the cable setup is great but going off that technician he definitely knows his stuff.

[@BenzinioB]

Well this is interesting product didn't know it exist. But does the installing of catch can ruin the guarantee of a new car? And can it be mounted in diesel hatchback not just big 4x4

[@brettheath3182]

Easy way is to ask vehicle manufacturers service department. Yes will need custom kit for hoses. Don't buy a fake provent get German made mann hummel provent 200

[@slavkoradovanovic6751]

So the engine tolerates the temperature when you press the pedal, then the EGR is turned off, but it cannot cope with the temperature when you are cruising at low revs?

[@wooblebloc]

Save your car. Block the EGR. That’s my motto.

[@steverx4460]

It doesn't stop oil from your pcv valve. As he said - all you need is a catch can.

[@Browndogdiesel]

Send it straight to the chassis rail

I can't tell if they're saying EGRs are a good thing because they have to or actually believe they are.

[@paultrend]

What I dont understand is why is the crank case overpressure fed back after the catch-can into the motor and not just off into the air...?

[@moisty254]

I installed a catch can and did EGR delete. Then I did an intake clean and also remove D swirl flaps coz they're known to come loose and get sucked in. 79k km. It was pretty sooty. I'm still concerned about valve seats and piston heads.

[@marcusbarnes5929]

Did you remove the EGR completely from engine, or just get it turned off in the tune, or use blank plates.?

[@jaycristaudo6061]

so why dont they install factory catch can?

[@FlashTechEngineering]

Don't get scammed by adding a catch can.. the oil is important part of lubrication and cleaning process comes down to poor maintenance, irregular oil changes and worn injections.. this is only a band aid patch job, look deeper into the real issues

[@praetorian3571]

Catch can is the modern engine fix snake oils!! It could severely damage the engine when it fails, and like so many other engine parts, they will fail and the cost to repair the engine will run into thousands of dollars.
